The suitcases came from Caracas aboard an Air France flight to Paris, but did not match any of the passengers on board, CNN affiliate BFMTV reported.

"Several" people have been taken in custody, French Interior Minister Manuel Valls told reporters Saturday.

Authorities worked with Spanish, British and Dutch police on the investigation, BFMTV said.

This case "illustrates the importance of strengthening International cooperation in the fight against traffickers," Valls said.

Venezuelan authorities are also investigating. The Public Ministry said prosecutors will investigate, along with the Counterdrug Command of the National Guard in Simon Bolivar International Airport, to see if any criminal activity took place.
